CVE-2020-11762

Name of the Vulnerable Software and Affected Versions OpenEXR versions prior to 2.4.1

Description The issue is related to an out-of-bounds read and write in the DwaCompressor::uncompress function in ImfDwaCompressor.cpp when handling the UNKNOWN compression case. This can be exploited by a remote attacker to cause a denial of service.

Recommendations For versions prior to 2.4.1, update to version 2.4.1 or later to resolve the issue. As a temporary workaround, consider restricting the use of the DwaCompressor::uncompress function in ImfDwaCompressor.cpp until a patch is available.
